α-Synuclein is abundantly present in Lewy bodies, characteristic of Parkinson’s disease. Its exact physiological role has yet to be determined, but mitochondrial membrane binding is suspected to be a key aspect of its function. Electron paramagnetic resonance spectroscopy in combination with site-directed spin labeling allowed for a locally resolved analysis of the protein–membrane binding affinity for artificial phospholipid membranes, supported by a study of binding to isolated mitochondria. The data reveal that the binding affinity of the N-terminus is nonuniform
